1、安装工具
install_deps.sh
2、编译behavioral-model
./autogen.sh
./configure
make
[sudo] make install # if you need to install bmv2 //没意义
3、测试
make check
4、安装p4c-bm
git下载代码：https://github.com/p4lang/p4c-bm
sudo pip install -r requirements.txt
sudo pip install -r requirements_v1_1.txt if you are interested in compiling P4 v1.1 programs
sudo python setup.py install
derek@ubox16:~$ p4c-bmv2 --version
1.11.0-e389bd34
5、在mininet上运行
1）编译json
cd target/simple_router
p4c-bmv2 --json simple_router.json simple_router.p4
2）运行
cd mininet
sudo python 1sw_demo.py --behavioral-exe ../targets/simple_router/simple_router --json ../targets/simple_router/simple_router.json
mininet>pingall //不通
3）配置table
再开一个终端：
- cd targets/simple_router
- ./runtime_CLI < commands.txt
mininet> pingall
*** Ping: testing ping reachability
h1 -> h2
h2 -> h1
*** Results: 0% dropped (2/2 received)
4）读写表项
开一个终端：
cd tools
./runtime_CLI.py --thrift-port 9090
RuntimeCmd: show_tables
forward [implementation=None, mk=routing_metadata.nhop_ipv4(exact, 32)]
ipv4_lpm [implementation=None, mk=ipv4.dstAddr(lpm, 32)]
send_frame [implementation=None, mk=standard_metadata.egress_port(exact, 9)]
RuntimeCmd: table_info forward
forward [implementation=None, mk=routing_metadata.nhop_ipv4(exact, 32)]
